Transponder Chips
Transponder chips can be found in vehicles manufactured in the last 20 years. This is a little plastic piece in the head of your key that houses an RFID (Radio Frequency Identification) chip with an individual code for the specific vehicle you own.
The chip sends out a low-level radio signal when it is activated by an electromagnetic field. This signal then gets amplified by the specific antenna that is fitted around the ignition barrel of your car. This allows the computer in your vehicle system to determine if the transponder chip in the key is the correct one for your specific vehicle.

When the transponder key is inserted into the ignition barrel, a circuit within of the induction coil sends out an electrical signal. The signal will be absorbed by the chip, causing it to send a signal back to the car. If the computer on the car recognizes this signal as the correct one, it will turn off the immobilizer on the vehicle and allow the engine to begin.
If the car isn't able to recognize the transponder as being the proper signal, it will not start the engine and warn you with flashing lights and an alarm. This feature is designed to deter people from trying to tamper with the vehicle, however it isn't a foolproof security measure. A skilled and determined thief might be able bypass this system by using a special device to detect the signal.

You can program a keyfob in various ways based on the model and brand of your vehicle. You can sometimes do this yourself, but most newer automobiles require a dealer or professional locksmith to program a replacement or an additional fob.
When you press the button on a key fob, the microchip sends an indication to the receiver in the vehicle with which it is linked. The receiver compares this information with the signals that are allowed inside the fob, and either locks or opens the door. If the data does not match the fob's information, the car won't be allowed to drive.
After the car has been connected to a specific fob, it only accepts signals from that device. In turn, other fobs won't be able to work with the vehicle even though they appear similar. This is to safeguard the integrity of the car's computer system and to prevent unauthorised key fobs from taking control of the vehicle.
Most newer car dealerships will only accept cars with original fobs, or genuine replacements supplied by the manufacturer. This is because the only place with the knowledge to create an appropriate replacement fob is the service department of the dealer. However, some fobs from the aftermarket typically for older models with less sophisticated systems -- can be programmed by customers without the need of an authorized dealer.
